Which ingredient is commonly found in products for treating acne?

1. Vitamin E

2. Salicylic acid

3. Glycerin

4. Jojoba oil

The correct answer is: Salicylic acid

Salicylic acid is widely recognized as a primary ingredient in acne treatment products due to its effectiveness in exfoliating the skin and unclogging pores. It is a beta hydroxy acid (BHA) that penetrates deep into the pores, helping to dissolve the debris and oil that contribute to acne breakouts. By promoting exfoliation, salicylic acid not only helps to reduce existing acne but also prevents new lesions from forming. The other ingredients mentioned serve different functions in skincare. Vitamin E is primarily known for its antioxidant properties and is often used to nourish and protect the skin but does not specifically target acne. Glycerin acts as a humectant, helping to keep skin hydrated, which is beneficial for overall skin health but not directly for treating acne. Jojoba oil is often used for its moisturizing properties and as a non-comedogenic oil, meaning it doesn’t clog pores, but it doesn’t address the underlying causes of acne like salicylic acid does. Thus, salicylic acid stands out as the correct choice for treating acne effectively.
